  1. Before starting, please note the handling precautions below.

      Caution Icon Caution:

      • Handle cartridges with care. Toner is free to spill out of a toner cartridge when it is in the locked position.

      • Be aware that during removal or cleaning, toner powder could get onto your hands, clothing or work surfaces.

      • Prepare a clean, level work surface before starting, and put down paper if required.

      • You may need a soft, dry, lint-free cloth with which to clean the cartridges.

      • Do not touch the toner. Keep the toner away from your eyes. If toner gets on your skin or clothes, wash it off with soap and water immediately.

      • If toner is spilled, use a broom and dustpan or a damp cloth with soap and water to clean it up. Because the fine particles can cause a fire or explosion if they come into contact with a spark, do not use a vacuum cleaner.

      Caution Icon Caution:

      We recommend using genuine Epson toner cartridges. Using non-genuine consumable products may affect the operation of your printer. Epson are not liable for any damages or problems arising from the use of consumable products not manufactured or approved by Epson.
